PRECAUTIONS FOR DIAGNOSIS

●

Before performing diagnosis, always read precautions. Refer to

GI-4, "General Precautions"

●

If ABS actuator and electric unit (control unit), steering angle sensor, steering system parts, suspension
system parts, or tires have been replaced, or if alignment has been adjusted, be sure to adjust neutral
position of steering angle sensor before driving. Refer to

BRC-46, "Adjustment of Steering Angle Sensor

Neutral Position"

●

After diagnosis is finished, be sure to erase memory. Refer to

BRC-67, "ERASE MEMORY"

●

When checking continuity and voltage between units, be sure to check for disconnection, looseness,
bend, or collapse of connector terminals. If any malfunction is found, repair or replace connector termi-
nals.

●

For intermittent symptoms, possible cause is malfunction in harness, harness connector, or terminals.
Move harness, harness connector, and terminals to check for poor connections.

●

If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal.

●

To use CONSULT-II to perform self-diagnosis of ABS actuator and electric unit (control unit), active tests,
or work support, first stop work, then connect CONSULT-II and select “ABS”.

●

While self-diagnosis results of CONSULT-II shows malfunction, if CONSULT-II active test is performed, an
engine system error may be indicated. In this case, start engine to resume the normal screen.

●

VDC/TCS/ABS system electronically controls brake operation and engine output. The following symptoms
may be caused by normal operations:

●

When CONSULT-II is used, ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp may be
ON/OFF.

Symptom

Symptom description

Result

Motor operation noise

This is noise of motor inside ABS actuator and electric unit (control unit).
Slight noise may occur during VDC, TCS, and ABS operation.

Normal

When the vehicle speed goes over 20 km/h (12.5 MPH), the motor and
valves operating noise may be heard. It happens only once after ignition
switch is ON. This is a normal status of the system operation check.

System operation check noise

When engine starts, slight “click” noise may be heard from engine compart-
ment. This is normal and is part of system operation check.

Normal

VDC/TCS operation
(SLIP lamp Blinking)

TCS may activate momentarily if wheel speed changes when driving over
location where friction coefficient varies, when downshifting, or when fully
depressing accelerator pedal.

Normal
Cancel the VDC/TCS
function for the inspec-
tion on a chassis dyna-
mometer.

For inspection of speedometer or other instruments, press
VDC OFF Switch to turn VDC/TCS function off.

When accelerator pedal is depressed on a chassis dynamometer (fixed
front-wheel type), vehicle speed will not increase. This is not normal. It is
result of TCS being activated by stationary front wheels. Warning lamp may
also illuminate to indicate “sensor system error”. This is also normal, and is
the result of the stationary front wheels being detected. To be certain,
restart engine, and drive vehicle at 30 km/h (19 MPH) or above. Make sure
that warning lamp does not illuminate.

Basic Inspection

NFS000GK

BRAKE FLUID LEVEL, LEAKS, AND BRAKE PADS

Check fluid level in the brake reservoir tank. If fluid level is low, refill the brake fluid.

Check the brake piping and around the ABS actuator and electric unit (control unit) for leaks. If leakage or
seepage is found, check the following items.

●

If ABS actuator and electric unit (control unit) connection is loose, tighten the piping to the specified
torque and make sure there are no leaks.

●

If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-conduct the leak inspection to make sure there are no leaks.

●

If there is leakage or seepage at any location other than ABS actuator and electric unit (control unit)
connection, wipe away leakage or seepage with clean cloth. Then inspect again and confirm the there
is on leakage.

●

If there is leakage from ABS actuator and electric unit (control unit), wipe away leakage or seepage with
clean cloth. Then inspect again. If there is leakage or seepage, replace ABS actuator and electric unit
(control unit).

CAUTION:

ABS actuator and electric unit (control unit) body can not be disassembled.

Check brake disc and pads. Refer to

BR-28, "Removal and Installation of Brake Pad"

in “Front Disc

Brake” and

BR-34, "Removal and Installation of Brake Pad"

in “Rear Disc Brake”.

POWER SYSTEM TERMINAL LOOSENESS AND BATTERY

Make sure the battery positive cable, negative cable and ground connection are not loose. If looseness is
detected, tighten the piping to the specified torquer. In addition, check the battery voltage to make sure it has
not dropped and the altimeter is normal.

ABS WARNING LAMP, VDC OFF INDICATOR LAMP, BRAKE WARNING LAMP AND SLIP INDI-
CATOR LAMP

: ON

–: OFF

Note 1: Brake warning lamp will turn on in case of operating parking brake (switch turned on) or of actuating brake fluid level switch
(brake fluid is insufficient).

ABS operation
(Longer stopping distance)

On roads with low friction coefficients, such as snowy roads or gravel
roads, vehicles with ABS may require a longer stopping distance. There-
fore, when driving on such roads, avoid overconfidence and keep speed
sufficiently low.

Normal

Insufficient feeling of acceler-
ation

Depending on road conditions, driver may feel that feeling of acceleration is
insufficient. This is because traction control, which controls engine and
brakes to achieve optimal traction, has the highest priority (for safety). As a
result, there may be times when acceleration is slightly less than usual for
the same accelerator pedal operation.

Yaw Rate/Side/Decel G Sensor

NFS000GQ

CAUTION:

Sudden turns (such as spin turns, acceleration turns), drifting, etc. may cause yaw rate/side/decel G
sensor circuit indicate a malfunction. However this is not a malfunction if normal operation can be
resumed after restarting engine.

INSPECTION PROCEDURE

CHECK SELF-DIAGNOSTIC RESULTS

Check self-diagnostic results.

CAUTION:

When on a turntable, such as at a parking structure entrance, or when on a moving object with engine
running, the VDC OFF indicator lamp might turn on and self-diagnosis using the CONSULT-II yaw rate
sensor system malfunction might be displayed, but in this case there is no malfunction with yaw rate/
side/decel G sensor circuit. As soon as the vehicle leaves the turntable or moving object, restart
engine to return the system to normal. And after doing spin turns or acceleration turns with VDC
“OFF” (VDC OFF switch “ON”), too, the results will return to a normal state by restarting vehicle.

Is above displayed in the self-diagnosis display?

YES

>> GO TO 2.

>> INSPECTION END

CHECK CONNECTOR

Turn ignition switch “OFF”.

Disconnect yaw rate/side/decel G sensor connector M61 and ABS actuator and electric unit (control unit)
connector E24 and check terminals for deformation, disconnection, looseness, and so on. If there is an
error, repair or replace terminal.

Reconnect connectors and then perform the self-diagnosis.

OK or NG

>> INSPECTION END.

>> GO TO 3.
